JACKSON B. ATKINSON, OF AUSTIN, TEXAS.

EXHIBITOR.

Application filed December 11, 1915.

To all whom t may concern:

Be it known that I, JACKSON B. ATKIN- soN, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements inExhibitors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in exhibitors and particularly for exhibitors adapted for use on motor vehicles toexhibit road maps when touring.

Another object of the invention is to provide a device which is capable of receiving and exhibiting separate cartridges or rolls of road maps so that touring in unknown countries by motorists will be materially simplified.

A further object of the invention is to provide a device which is adapted to pass over and illuminate the background to render thesame useful at night.

Still another object of the invention is to provide a device which is particularly simple in construction and may be easily and cheaply manufactured and installed.

. `Still another object of the invention is toV provide a device provided with a means to 'release the same from the gearing driving it so as to enable the map to be set by hand.

Still anotherobject of the invention is to provide a device in which the illuminating means may be used, as a trouble lamp or for other illuminating purposes.

With these and other objects in view, the invention consists in the novel combination and arrangement of partsV which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a face view of an exhibitor constructed in accordance with this invention.

Fig. 2 is a top plan view of the device showing the cover removed.

Fig. 3 is a longitudinal sectional viewon line 3-3 of Fig. 2. Y

Fig. 4 is a face view of the disk on which the cartridge or spool is mounted.

Specification of Letters Patent.

Patented Aug. 14, 1917.

Serial No. 66,328.

Fig. 7 is a detail end view of the knob used to disengage the clutch member and the pawl for holding said clutch member disengaged.

Referring to the drawings the numeral 1 designates the base `of the device provided at opposite terminals with curved upturned ends 2. Suitable side walls 3 are connected to the base and between the ends as clearly illustrated in Figs. 2 and 3. The cover is designated generally by the numeral 4 and comprises the top 5 provided with the down-v wardly inclined ends 6 terminating in the curved portions 7 which aline with the curved portions 2 of the bottom 1 and are provided with suitable latches 8 which are adapted to hold the base and upper sections together. Formed in the top wall 5 to one side thereof is an opening 9 covered with a glass or transparent panel 10 through which the characters on the road map may be seen.

Mounted within the base member of the device is the frame 11 consisting of a lower bar 12 provided at one end with the upwardly and outwardly inclined bar 13 having the arm 14 formed at the upper terminal thereof. A suitable upwardly and outwardly inclined bar 15 extends upwardly from the point where the bar 13 joins the base 12 and this portion 15 terminates in the downward extension 16 which joins the upwardly curved member 17 at the end ofthe bar 12 opposite the bar 13. The point where the member 15 joins the member 16 is provided with an opening forming a bearing in which the shaft 18 is journaled as clearly illustrated in the drawing. A frame similar to the frame 11 designated generally by the numeral 19 is secured in the opposite side of the base member and coperates with the frame in rotatably mounting the spool. A shaft 20 is journaled in the arm 14 in hori- Zontal alinement with the shaft 18 as clearly shown in Fig. 3. APivotally mounted on the shaft 20 and extending upwardly therefrom is an arm 21 provided at its upper end with a pivot pin 22 on which the roller 23 is rotatably mounted. This roller is rotatably mounted at its opposite end to an arm 24 mounted in a similar manner on the frame 1 19. The lower end of the arms 21 and 24 are each provided with the stops 25, which are adapted to engage the stop pins 26 carried by the frame to prevent the arms from moving inwardly beyond a predetermined point. A similar pair of arms is mounted at the opposite ends, of the frames 11 and 19 and the upper terminals thereof support the roller 27 which corresponds to the roller 23 hereinbefore described. The upper ends of each of the pivoted arms are provided with the loops 28, the use of which will appear as the description proceeds.

A frame 29 is secured intermediate the frame 11 and one of the side walls 3 and a similar frame 30 is positioned inwardly from the frame 29. The outer terminal of the shaft 31 is rotatably mounted in the frames 11 and 30 while the stub shaft 18 is rotatably mounted in the frames 32 and 29, the frame 32 correspondin somewhat to the frame 11. A suitable c utch member 33 is secured to the outer end of Ythe shaft 31 and is adapted to coperate with the clutch member 34 carried by the inner end of the stub shaft 18. This shaft is slide-ble through its journal bearings and a spring 35 is adapted y to normally urge the shaft inwardly to cause the clutch members 33 and 34 to engage. In order to disengage the clutch members, the knob 36 is positioned on the outer side of the casing-1 and a latch dog 37 is adapted to engage between theinner end of the knob and the wall 3 to prevent the inward movement of the clutch member 34-toward the clutch member 33, when the device is being set.

A suitable gear 38 is secured to the shaft 18 and meshes with the gears and pinions of the gear train designated generally by the numeral 39 which is driven by the worm gear 40 mounted on the shaft 41. This shaft 41 is driven by a flexible chain or shaft 42 carried within a suitable housino 43 and connected to one of the rear wheels of the Vehicle on which the device is used.

In order to provide a support for the end of the spools opposite those supported on the shafts 2() and 31 suitable pins 44 provided with the heads 45 are slidable through one of the side walls and through the openings in the frame 19. These pins carry the collars 46 which form abutments for the inner ends of the coil spring 47 which normally exert inward pressure on the pins to cause them to enter openings in the spools. The inner terminal of each of the shafts 2O and 31 carries a disk 48 provided with a central transversely extending rib 49 formed on the inner face thereof which is adapted to engage in the slot in its respective spool whereby upon rotation of the shaft the spools will be revolved.

\ In order to illuminate the device at night there is provided the reflector 50 provided centrally with a lamp socket 51 in which the lamp bulb 52 is mounted. A suitable chamber 53 is formed beneath the lamp bulb and `is adapted to retain the flexible cord carryingjthe current to the lamp to allow for the movement of the reflector. Each corner of the reflector carries a Vhook 54 which is adapted to engage in the eyes 28 carried by the arms 21. Y

It will be apparent from the foregoing that in use the spools are placed in position on their respective shafts and pins and the springs 47 will force the pins into engagement with the spools and hold the same in proper engagement with their respective disks 48. Upon releasing the pawl 37 and permitting the shaft 18 to` move inwardly under the influence of the spring 35, it will be seen that the rib on the face of the clutchv member 34 will engage the teeth on the face of the clutch member 33, thereby causing the shaft 31 to revolve and revolving the empty spool mounted thereon to cause said spool to revolve Vwhen the gear train is set in motion. hen it is desired to set the map, it is evident that the knob 36 is pulled outwardly so that the pawl 37 will hold the shaft 18 back against the tensionof' the spring 35 and keep the clutch members 33 and 34 separated. The crank 54 is then rotated, therebv rotating the shaft 55 and causingthe gear 56 to drive the pinion 57 on the shaft 20, thereby rotating the same and adjusting the map. 4

`It will be apparent from the foregoing that a particularly simple and efficient mapl exhibitor is provided which is adapted for use on motor vehicles and vwill accurately indicate the direction to be taken and avoid the possibility of motorists becominglost or from straying from the proper road.V

`lVhile in the foregoing'there has vbeen shown and described the preferred embodiment of this invention, it is tobeunderstood that such changes may be made in the combination and arrangement ofpart-s as will fall within the spirit and scope of the appended claims. Y i i vWhat is claimed is:-
